The question was:

Now, what is the type of true and false, when using:

$ cat /usr/lib/gcc/i486-linux-gnu/4.1.2/include/stdbool.h
[...]
#define true 1
#define false 0

I fail to see how the hypothetical usage of the # operator is
relevant to the question. The types of true, false, and INT_MAX
are all the same: int.

My point is that we don't have a typed identifier at all. We have
created another representation for the digit 1 (or for 0). Yes,
the unadorned use of such digits can generate an int type constant,
however we are not limited to such unadorned use.

The characters 'true' are simply another glyph for the digit '1'.
